Title:
MOBILITY MANAGEMENT OF MULTIPLE CLUSTERS WITHIN WIRELESS COMMUNICATIONS NETWORK
Document Type and Number:
Japanese Patent JP2014042256
Kind Code:
A
Abstract:

To provide a method of coping with cluster collisions in a wireless communications system.

A wireless communications network includes a first cluster of sectors with a target sector and a supporting sector. A multicast communication session is carried within both the target and supporting sectors. A second cluster can be included within the network for supporting the same multicast communication session that includes its own target and supporting sectors. The first cluster transmits multicast media on a first interlace-multiplex (IM) pair of a downlink broadcast channel (BCH), and the second cluster transmits multicast media on a second IM pair of the downlink BCH. If sectors of the first and second clusters overlap, the network controls a manner in which the first and second clusters carry the multicast media.
